- Scientists from the Department of Science and Technology developed spent tea leaves into plywood glue
- The researchers collected tea leaves, proceeded to dry, mill, and mix these with urea formaldehyde resin
- They proved that the tea leaves can be a cheaper replacement for wheat flour
Filipino scientists have found a new use for discarded and spent tea leaves by turning it into cheap and reliable additive in producing plywood adhesives.
Scientists from the Forest Products Research and Development Institute (FPRDI) of the Department of Science and Technology, according to a report, found that spent tea leaves “retain much of its valuable fiber and protein components even after multiple uses”; making it a very important material for plywood adhesive.
To complete the study, the researchers collected the tea leaves, which usually end up in the landfill, from a local beverage manufacturing plant. They then dried the leaves, milled them and mixed them with urea formaldehyde resin.
The researchers further proved that the tea leaves can be a cheaper replacement for wheat flour “when simultaneously used as extender and filler in locally-produced plywood adhesives.
Under an agreement between FPRDI Director Romulo Aggangan and IM Wood headed by President Maria Cristina Huang, the discovery was sent for testing in a manufacturing of plywood panels of Impasug-ong Integrated Wood Processing and Plywood Manufacturing Inc. (IM WOOD).
It will determine the effectiveness and adhesive capability of the glue mixture. The amount of money that will be saved using the mixture will also be determined during the test. It was also revealed that it will undergo a year-long testing.
“We will test if the plywood produced will pass national and global standards for shear strength, formaldehyde emission and termite resistance. Formaldehyde is a chemical compound found to cause certain types of cancer in humans,” Project Leader Engr. Juanito Jimenez, Jr. said in a report; expressing optimism about the turnout of the project.
